Stable exponential cosmological solutions with two factor spaces in the Einstein-Gauss-Bonnet model with a -term
V. D. Ivashchuk, A. A. Kobtsev
We study -dimensional Einstein-Gauss-Bonnet gravitational model including the Gauss-Bonnet term and the cosmological term . We find a class of solutions with exponential time…
Nonlinear electrodynamics, regular black holes and wormholes
K. A. Bronnikov
We consider spherically symmetric configurations in general relativity, supported by nonlinear electromagnetic fields with gauge-invariant Lagrangians depending on the single invar…
On generalized Melvin solutions for Lie algebras of rank 3
S. V. Bolokhov, V. D. Ivashchuk
Generalized Melvin solutions for rank- Lie algebras , and are considered. Any solution contains metric, three Abelian 2-forms and three scalar fields. It is gov…
Inhomogeneous compact extra dimensions
K. A. Bronnikov, R. I. Budaev, A. V. Grobov +2
We show that an inhomogeneous compact extra space possesses two necessary features --- their existence does not contradict the observable value of the cosmological constant i…
Dyonic configurations in nonlinear electrodynamics coupled to general relativity
K. A. Bronnikov
We consider static, spherically symmetric configurations in general relativity, supported by nonlinear electromagnetic fields with gauge-invariant Lagrangians depending on the sing…
Wormholes with fluid sources: A no-go theorem and new examples
K. A. Bronnikov, K. A. Baleevskikh, M. V. Skvortsova
For static, spherically symmetric space-times in general relativity (GR), a no-go theorem is proved: it excludes the existence of wormholes with flat and/or AdS asymptotic regions…

We construct explicit examples of globally regular static, spherically symmetric solutions of general relativity with a phantom scalar field as the source of gravity, describing tr…
Stable exponential cosmological solutions with zero variation of G in the Einstein-Gauss-Bonnet model with a Lambda-term
K. K. Ernazarov, V. D. Ivashchuk
A D-dimensional gravitational model with a Gauss-Bonnet term and the cosmological term Lambda is considered. By assuming diagonal cosmological metrics, we find, for certain fine-tu…
Duality between k-essence and Rastall gravity
Kirill A. Bronnikov, Julio C. Fabris, Oliver F. Piattella +2
The k-essence theory with a power-law function of and Rastall's non-conservative theory of gravity with a scalar field are shown to have the same solutions for the…
Neutrino Fluxes from a Core-Collapse Supernova in a Model with Three Sterile Neutrinos
A. V. Yudin, D. K. Nadyozhin, V. V. Khruschov +1
The characteristics of the gravitational collapse of a supernova and the fluxes of active and sterile neutrinos produced during the formation of its protoneutron core have been cal…
